Question 3

+5 marksOne correct option

trains is a dictionary with train number as key mapped to a list of stations which that train runs through. For example, trains = { 12281: ["Bhubaneswar","Balasore", "Adra", "Varanasi", "Kanpur", "New Delhi"],......}. In this example, the train with train number 12281 starts from Bhubaneswar and reaches New Delhi via Balasore, Adra, Varanasi, and Kanpur.

At the end of execution of the code below, L stores the names of stations through which the maximum number of trains pass. Choose the correct fragment to complete the pseudocode.
It is a Multiple Choice Question. (MCQ).
